After upgrading my work computer til Ubuntu 17.04 I'm no longer able to restore the previous session in Firefox. If I click Restore, Firefox greys out after a couple of seconds, and a few seconds later other services seem to stop as well. I've noticed that dmesg shows errors that seems to originate from the kernel when this happens.
I've attached a photo of the screen with the bug messages from dmesg. It claims that there is a kernel bug on line 129 of linux/swapops.h which seems to indicate that it is trying to migrate an unlocked page for some reason.
The machine has 32GB of RAM, and the crash occurs right after reboot when starting Firefox, so there should be plenty free memory.
